Vehicle display device

Abstract

To provide a vehicular display device capable of displaying information required upon the occurence of abnormality even in such a case that a display part is singe setting.SOLUTION: In a vehicular display device including a display control part 140 which controls the display state of an image 111 on a display part 110 based on drawing data RL1 acquired from a deserializer 130, the display control part can perform on-screen display to the display part, based on design data for display stored preliminarily, a backlight control part 120, the deserializer and the display control part also function as a detection part 150 which can detect an accident mode with respect to the predetermined drawing data, and the backlight control part, when the accident mode is detected, instructs the display control part so as to perform the on-screen display onto a black image 111j of the display part by using a vehicle information acquired by the black light control part from the vehicular control part and the design data.SELECTED DRAWING: Figure 1

Claims

1. A single display unit (110) that displays an image (111) related to vehicle information (R2), A backlight control unit (120) controls the lighting state of the backlight (110b) of the display unit, An input unit (130) to which drawing data (RL1) relating to the vehicle information output from the vehicle control devices (11, 12) is input, A vehicle display device comprising a display control unit (140) that controls the display state of the image in the display unit based on the drawing data acquired from the input unit, The display control unit enables on-screen display for the display unit based on the minimum necessary design data for display that is stored in advance. The backlight control unit, the input unit, and the display control unit also function as a detection unit (150) capable of detecting a predetermined failure mode related to the drawing data. The backlight control unit, when it detects the failure mode, instructs the display control unit to use the vehicle information acquired by the backlight control unit from the vehicle control device and the design data to perform the on-screen display on the black image (111j) of the display unit.

2. When the failure mode is detected, the backlight control unit turns off the backlight to form the black image on the display unit. The vehicle display device according to claim 1, wherein, after forming the black image, the display control unit is instructed to perform the on-screen display.

3. A single display unit (110) that displays an image (111) relating to vehicle information (R2), A backlight control unit (120) controls the lighting state of the backlight (110b) of the display unit, A display control unit (140) receives drawing data (RL1) relating to the vehicle information output from the vehicle control devices (11, 12) and controls the display state of the image on the display unit based on the drawing data, A vehicle display device comprising an input unit (130) into which the drawing data is input from the display control unit, The display control unit enables on-screen display for the display unit based on the minimum necessary design data for display that is stored in advance. The vehicle is provided with a control unit (14) that acquires the vehicle information from the vehicle control device, forms it into drawing data in the calculation unit (14a), and outputs the drawing data to the display control unit via the output unit (14b). The display control unit is located in the control unit. In the control unit, the output unit and the display control unit also function as a detection unit (150) that enables the detection of a predetermined failure mode related to the drawing data. The backlight control unit, when it detects the failure mode, instructs the display control unit to use the vehicle information obtained by the calculation unit from the vehicle control device and the design data to perform the on-screen display on the black image (111j) of the display unit.
